"HOP ON HOP OFF"
Dublin City Tour Tip by shortysboy

The Red, HOP ON, HOP OFF busses and their live guides were great. One note of caution, they say one lap typically takes 90 minutes but these buses are subject to traffic congestion like every other vehicle. They have special lanes and priority in some place but not everywhere. I highly recommend them for information, convenience and edutainment but realize it might take longer than planned to get from A to B and it's not their fault.
